Final answer:
The type of management decision requiring specific actions is tactical, C. Tactical decisions involve concrete actions and resource management to achieve parts of a strategic plan.
Step-by-step explanation:
The type of management decision that requires specific actions is C. tactical. Tactical decisions are focused on the implementation of specific actions necessary to achieve a part of the strategic plan. They require managers to decide on the activities, processes, and operational functions that will effectively implement the larger strategies set by the organization, usually within a short to medium time frame.
Tactical decisions are distinguishable from strategic decisions, which are broader and set the overall direction for the company. Conversely, tactical decisions are more concrete and action-oriented, often involving the allocation and management of resources to achieve strategic objectives. Predictive and departmental decisions can be a part of tactical decisions, but not all such decisions are specifically action-driven as tactical decisions are.
